The article is about a 15 year-old schoolboy, named Akmol Miah, who killed his ex girlfriend when he was 14 years old. He has now received his punishment and was jailed for at least 23 years. Miah targeted 15 year-old Maleha Masud in revenge because she ended their three-month relationship and refused to get back together. Miah got help from his 21 year-old cousin and together they poured petrol through the front letterbox at Masud’s home in south London. Her mother, and 2 brothers managed to survive, but both Maleha and her sister Nabiha died in hospital. Her mother also believes that both of the boys should have gotten life sentence.

I also believe that both of them should have gotten a life sentence. The act that both of them committed is unforgivable and that at such an early age. The 21 year-old should have known better. The 14 year-old clearly has shown that he is mentally disturbed, not only by seeking revenge for his girlfriend dumping him, but also for taking a picture of the burnt down house and then saving it as his wallpaper on his computer. I also feel sorry for the mother, who has lost two of her kids. The boy had been threatening the family prior to the assault and the family should have gone to the police right there. Still I feel that the boy should have been punished more harshly than he has right now
